Abstract

Purpose: The purpose of this review is to investigate the relationship between life-space mobility and cognition in older adults.

Methods: MEDLINE, Embase, CINAHL, and PsycINFO were searched through December 2018 for studies containing measures of life-space mobility and cognitive function. Two independent reviewers screened studies. Eligible studies were combined using a random-effects model, and heterogeneity was assessed using the I ².

Results: Thirty-five articles were identified for review. A moderate and statistically significant association (pooled r = 0.30, 95% confidence interval 0.19 to 0.40.) was observed between life-space mobility and cognition among nine studies. Life-space mobility demonstrated small-to-moderate associations with domain-specific cognitive functioning, particularly executive function, learning, memory, and processing speed. Furthermore, individuals who had restricted life-space mobility (Life-Space Assessment ≤ 40) experienced a steeper decline in cognition (β = 0.56 and p = 0.0471) compared to those who did not (Life-Space Assessment ≥ 41).

Conclusion: This review examined the association between life-space mobility and cognitive function in older adults. The results suggest that a moderate relationship between life-space mobility and cognition exists, whether adjusted or unadjusted for covariates such as sociodemographics, mental health, functional capacity, and comorbidities.

研究老年人生活空间流动性与认知功能之间的关系:一项系统综述。

目的:探讨老年人生活空间活动能力与认知能力的关系。方法:检索MEDLINE、Embase、CINAHL和PsycINFO截至2018年12月包含生活空间流动性和认知功能测量的研究。两名独立评审员对研究进行了筛选。使用随机效应模型对符合条件的研究进行合并，并使用i2评估异质性。结果:35篇文章被纳入综述。9项研究中，生活空间流动性与认知之间存在中度且有统计学意义的相关性(合并r = 0.30, 95%可信区间0.19 ~ 0.40)。生活空间移动性与特定领域的认知功能，特别是执行功能、学习、记忆和处理速度有小到中等程度的关联。此外，生活空间流动性受限(life-space Assessment≤40)的个体认知能力下降幅度明显大于非生活空间流动性受限(life-space Assessment≥41)的个体(β = 0.56, p = 0.0471)。结论:本综述探讨了老年人生活空间活动能力与认知功能之间的关系。结果表明，生活空间流动性与认知之间存在适度的关系，无论是否调整了社会人口统计学、心理健康、功能能力和合并症等协变量。
